GMK sets have two trays, so be sure to check both trays for any missing keys before reaching out.
In the case of missing caps, please include a picture of the caps that you received.
In the case of damaged caps, please include pictures of the affected caps.
Sometimes the caps just have a bit of the tray material stuck on them, this can be easily wiped off.
Please note: we are only able to provide support for this issue to the original customer that originally made the purchase.
